[PATCH 4/4] doc/technical/whyperl: note Perl 7 announcement

[Eric Wong <e@yhbt.net>]

Right now[1] the Perl upstream plan is to maintain 5 compatibility
in Perl 7 for at least 5 years[1], and perhaps drop it when Perl 8
comes along.  That said, distros may pick it and maintain 5 on their
own given the vast amounts of perfectly good legacy code out there.

   Perl had fewer breaking changes than Python or Ruby; we
   expect that trend to continue given the inertia of Perl 5.

+  We'll continue to monitor and adapt to the situation around
